Samples of wet precipitation were collected to assess the presence of metals in the wet precipitation in peenya industrial zone, Bengaluru during 12 rain events, on 2015, south-west monsoon. Collected samples were analyzed for pH and metals. The pH ranged between 4.67 – 6.60, which depicted the acidic nature of wet precipitation with a mean pH of 5.08 and presence of metals in the wet precipitation in the following order Iron > Zinc > Manganese > Aluminum > Chromium > Copper > Nickel > Lead > Cadmium. The acidic nature of wet precipitation has resulted in the solubility of metals in particulate matter. Iron was identified to be the dominant species among all the metals.
